Since the nation declared independence and achieved it with military force, war has affected almost every person in the United States. This gallery exhibits many examples of military equipment, both U.S. and foreign, as well as life in the military. The Civil War is featured with a replica of an ironclad that operated on the nearby Mississippi River. A PT-17 Stearman airplane from WWII is suspended in the south atrium as a tribute to the hundreds of pilots who received their flight training at a nearby military airfield. Several videos record the military experience of area service personnel.
